Referring to the drawingsandlin detail, 4AV designates aspoolgbox in whichare arranged twotrackers B and C, eachfhaving a set 4of' note controlling or playingV apertures. As shown', thetrackers are arranged one above the other, but Vthis arrangement is n u PatenteaNov. 9, 1915./ 'i 4Applim'ion nea-February 6,1913. seriaiNomisia l Y not necessary, as .they may be arranged in c i any convenient relation l'to leach other. A- set .of the' usual music roll bearingsilO-l is arranged in. the ySpool box'in which a' music spooLD having va perforated note`- sheet E wound 'thereon vcan jbe placed. F

designates .a take-upnroll fori/drawing said note-.sheet forward over the tracker B, which take-uproll is journaledin bearings in the spool box. .The take-uproll F isvpro'vided witha gear-.11 engaging which is a .pinion 12 mounted onthe end ofan aXfi'allymow able shaft 13 which has a sprocket-wheel 14sV on the endthereofto which power is supplied byy sprocket chainvll and-sprocket wheel 16 arrangedlon theshaft 17 of apneumatic motor G secured to'thefr'ame. of the machine. This .motorvmay' be of the j usual type'and preferably isv arranged with its pneumaticsI extending'v horizontally.` Secured on. said shaft 13 is agrooved `collar 18 having a projecting Apin' 19: Loosely mounted on said'shaft liis 'a sprocket gear V20 which is engagedbyza sprocket chain 21' which runs around apinionQQswhich is secured to the right-hand bearing orvshaft which supports lthe music spool D. The sprocket gear QOis held in place Iaxially byI an arm which engages a fioovetherein f K. A lever 23 is pivoted .to a'beari'ng 24 and K has a pin 25 engaging the groove ink the colswitchedfrom one notelsheet to the otherlat any time so as yto change the t'uiie'or'melody'l which sometimes isdesirable sov that the 'operator can change thetune to follo'w changes i of the lever isthrown to the left, therpinion 12 will engage the gearll and as the motor" Gris operated, the take-up roll F will be ,ro-

tated to draw the note-sheety `forward overf the 'tracker B and wind thev same up Von said roll,` and as the pin 19on the groove'd' collar. 18 does not engage the pinf`26 -On ythe sprocket 20 during this operation, the

iOs

the sprocket 20 will not be rotatedi vWhen ,y

the upper end of the lever is thrown Vto the right, the pinion 12 will be disengaged from Y' thegear '11 andthe grooved collar' will be moved to "the right so that its pin 19 willv` engage the pin 26 on the sprocket 20; hence power will be transmitted from the motor Cr to turn the music spool D in a direction to in which a music spool D can be arranged per end of the lever 23 is shifted to the4 so that `a perforated note-sheet E can be drawn over the lower tracker C and wound up on a. take-up roll F. This take-up roll F has a gear 110 thereon'engaged by a pinion 120 mounted on a slidable shaft 130 having a sprocket wheel lll() thereon which is driven by a sprocket chain 150 from a sprocket gear 160 mounted on the shaft 170 of a pneumatic motor G. This pneumatic motor G preferably is arranged to stand vertically. Secured on said slidable shaft 130 is al grooved collar 180. A sprocket wheel 200 Ais loosely placed on said shaft 130 and connects by a sprocket chain 210 to a sprocket pinion 220 mounted on the right-v hand bearing 100. The lower end of the lever 23 is provided with a pin250 which engages into the groove of the collar 180 and the sprocket 200 is provided with a pin 2G() which can be engaged bythe pin 190 of the grooved collar 180. Thus it will be seen that, when the upper end of the lever 28 is rocked to the left, the upper' mechanism will be operative to draw the notesheet E forward over the tracker B and the lower mechanism will be operative to draw the note-sheet E backwardly on the lower tracker C and rewind the same on the take-` up roll F Cn the other hand, if the upright, the upper mechanism will be operative to draw the note-sheet E backwardly over the upper tracker B and rewind the same on the music spool D, while the lower mechanism will be operative to draw the perforated note-sheet E forward over the lower tracker C on to the take-up roll F. To operate the lever 23 the followin mechanism is provided: A shortv shaft 2 1s Journaled in the left of the spool box and has a controlling lever H secured on the end thereof inside of the spool box. `On the end of the shaft 27 is arranged a lever 28 .from which extends upwardly a link 29 adpistably secured to which is a staggered arm 30 which connects bv link 8l to a pivoted bellv crank leverv 32 extending from which. isa linkBS. Adj'u'stably secured to. the hek tali-,Sa lies Streich eterea;-

to a pivoted lever 35, the upperl endof which has a pin 36 which lits into the grooved collar 180. By these connections, by throwing the upper tracker B and the lower notesheet E will be drawn backwardly or rewoundover the lower tracker C, as shown in Fig. 2, while by throwing the controlling lever H downward, the mechanisms will be set so that the note-sheet E will be drawn forward for playing over the lower tracker C, and the note-sheet E will be drawn backwardly over the upper tracker B or rewound on its music roll, this position of the parts being indicated in Fig. l.

It is also necessary, in connection with the mechanisms, to provide a switching mechanism to control the trackers so that only the tracker on which the note-sheet is being drawn forward for playing will be connected to the operating instrumentalities or pneumatics of the instruments; and it is also necessary to provide valve mechanism so that the penumatic motor which is operating to draw its controlled note-sheet forward for playing can have its speed governed, while the pneumatic motor which is operating to draw its controlled note-sheet backwardly or rewind the same can run at full speed. lt is also necessary and desirable to coordinate these instrumentalities so that they will be adjusted in unison. The mechanism for this purpose is arranged as follows :--l designates the wind chest and J the usual governing box in which there is arranged a tempo controlling valve N which is operated by link 36, lever 37, link 38, and finger lever 39. This latter lever also connects by link 4-0, lever All, shaft 4t2, lever 4.13, link ,4H to an indicator arranged in position to cooperate with the scale 46 so that the tempo adjustment of the instrument is readily discernible to the operator. The usual motor feed pipe 47 is connected to the top of the governing box J and the tension induced in this pipe is controlled by the governor and by the adjustment of the tempo valve, and hence the speed of the motor which is operating to draw its controlled note-sheet forward is regulated by the finger lever 39.

The pipe el? is connected to a pipe 48 which is connected to the lower side of a valve block K and to thenpper side of a valve block L.V Cooperating with the upper valve block K is a D- or slide valve M, and cooperating with the lower block L is a similar D- or slide valve N. These valves are held in position by springs 49. The link 33 connects to a bell crank lever 50 y which connects by a link-51 to the lower slide valve N and the two slide valves are @erected .together by links and .53. which.

insegnatil v are adjustably secured togetherby; 'a vcou# pling 54:. By this -arrangement,wvhen ,the

controlling lever H is in' its Aupper position, as shown 1n. Fig.V 2, the valvesM and l'N `are intheir lowest position to renderA the upper motor G' operativefor drawing the note-sheet E forward for playing, while when the controlling lever H is in its lower` position, the valves are inftheir upper posi-- tion, as indicated 1n Fig. 1 to make the lower motor Grr operativefor drawing the notesheet E forward for playing,l A pipe 55V is connected directly to the wind chest and to, a block 56feXtending from the lower valve block L, and the block 56 is connected by a pipe 57 to a pipe 58 extendingvrfrom the Y side of the upper valve block K. -j3assage 59 extends from the block 56 inside of the lower valve block Land a passage 60 eX- tends from thefupper pipe 58 intoy the upper.

ralve block K; A. passage 61 is formed-in the lower valvel block L, and la passage v62 in the upper valve `block K toconnect'to the pipe 48. VThe lower valve blockfL has a passage 68 and theupper valve block K has a passage Gat formed throughthe same. controlling handle-H is in itsiupper' position, the tension obtained by the` governing apparatus and adjustment of the tempo valve J. inthe pipe 471 will be connected'to the passage 64: and hence theupper motor G* i will-operate at a governedfspeed,V depending uponk the adjustment of the .tempo valve,`

while the directly connected pipe 55 will be connected to operatev the lower motor kG vat the full speed, depending upon the tension inthe windfchest. 1KWhen the handle H isin its lowerY position, the connection to.

'j the motors lwill be reversed.

Now referring to the switching `mechay nism which controls the connection of the tracker to the'operating instrumentalities ofthe instrumenhv and 66 designategtlie tubes extending from theaperturesgin the upper tracker B and V67-1-68designate tubesY I extending from the apertures in the lower tracker@- These tub-es are connectedl to a switch block 69 which is illustrated more particularly in the third sheet of thedraw' ings. Connected to this switch block are tubes 70 and 71 which extend to the pneu-1 `matics or playing mstrumentalities ofthe instrument.; V72 designates a valve carrier` which has a plurality of'valves 73 secured thereto. Eachvalve 73hasprojecting pins Tl-74g which t into' holes ,formed in the.

valve carrier 73 and aspring i75 is fitted on a teat formed on the valve to keep theA 6,0.

samein; position ony the ,valve `carrier 72.

Each valve ispreferably arrangedto have four passagesv76 therein so as to control the switching of fourtubes. f r When the carrier 72l is in its lowest position, as ,shownn yin `Fig. 6, Vthe tubes and T66 coming. from By thesek arrangements, when the the upper tracker Bare connected to. the

tubes 70.*171, while when the-valve carrier 7 is in its highest position, the tubes67-68 coming from the lower trackerv are connected tothelower tubes `-71.V Y

The valve carrier'is operatedbythe following Vconnectionsz-.The link 29 is connectedtov anl arm'77 secured on a'shaft 78 journaled in the back of the spoolboX secured` on which shaft are armsg79-79 which connectvbylinks 80-'80 tov the .valve carrier 72. rBy this arrangement, Awhen the con.

Y trolling lever H is in itsraised position, the

valve carrier72 willbein kits lower posi'- tion andthe upper tracker willv be "operavtively connectedfto the operating .pneumatics'l sol of the instrument and the lower trackercut out therefrom, while when the .controlling lever ll is in its lower position, the valve carrier `7 will be liftedto its upper position andthe lower tracker will Vbe opera.V

tively connected to the'.` operating lpneu-rv i matics-andV the upper tracker cut out.`

*Asthe handle vH, bythe connections above described, also y'gives thev proper. connection ofthe motors tothe wind chest, it, will be seenthat when the handle is raised and the uppjerftiia'cker is operatively connected,the upperfmctor G will work at the governed adjusted speed and the lower motor at full speed for 1 rewinding,"and that when the operating handle H is lowered and the lower tracker operatively connected, the lower ino- 'k torwill work at the governed adjusted speed. and the upper motor will work at full speed. rlhus all vthat is necessary to givethe proper adjustment between the cooperating instrumentalities is the `manipulation of the conjtrolling handle H. y. j y

It yis desirable,V additionally, toy provide and stopped in operation, and the follow-ing arm'Sl'is arranged inside of the-spoolv boX and' is formedy onlthe end lof a shaft 82,

which is j ournaled in the'spool boXandV in ar Vsuitable .bearing and which has an arm 83 sitionfthe valve block r`is cut olf from vconnection to the motor G. Hence, the, opera-` tion of the motor Gr, either at the governed adjusting speed obtained through the pipe 4E7orat full speed, as obtained through the'V pipe 55, is controlled by said arm 81. A similar arm 87 is arranged Vona shaft 88 secured to which is an arm 89 connected by links 90 and 91 having an adjustable cour vparts are provided for this purpose z-An y 105 means whereby each motor can be started 1 v:in the claims.

pling, to a valve 92 arranged between the lower valve block L and the lower pneumatic motor G. Hence, by the arm 87 the operation of the lower pneumatic motor G can be started and stopped either at the governed adjusted speed for playing, or at the full speed for rewinding. Therefore, by the mechanisms described, the results previously mentioned can be obtained.

For illustration, a music sheet E can be put in position to cooperate with the upper tracker B and the mechanism set in position to use this note-sheet by lifting the handle H. Arms S1 and S7 should be in elevated l position. After the upper note-sheet E is in position, the instrument is set in operation by lowering the arm 8l whereby playing will vtake place from the upper note-sheet and during playing the tempo can be controlled by lever 39. As this playing operation takes place, a note-sheet E can be placed in position tov cooperate with the lower tracker C. If while playing, it is desired to switch from the piece of music contained on the upper note-sheet to the piece of music contained on the lower note-sheet, all that is necessary is to depress the handle H and raise the arm 81 and lower the arm 87, when the operation will be practically instantly switched to the lower note-sheet and the tempo at which this note-sheet is played can be regulated through lever 39. Switching back can be done by lifting lever'H, lowering lever 81 and lifting lever 87. If while playing the upper note-sheet, it is desired to rewind the lower note-sheet and put a new piece in position, or for other purposes, all that is necessary is to lower the arm 87. Then playing is iinished with the upper note-sheet, the lower note-sheet can be set in operation. Similar manipulations can be made in connection with the lower notesheet; that is, the playing can be switched to the upper note-sheet and switched back to the lower note-sheet. The upper note-sheet can be rewound while playing from the lower note-sheet and when the playingis completed with the lower note-sheet, the instrument can be switched into operation in y connection with a new note-sheet placed in position relatively to the upper tracker. Thus, by the mechanisms described, playing can take place at any time, either from the upperor lower note-sheet and either notesheet can be rewound while playing is going on with the otherv note-sheet. Thus a compact, simple apparatus for the many purposes described, is obtained which can be manipulated and controlled by a comparativelv unskilled operator.
